BOOM BOOM POW TerraCycle makes mini Speakers ($13.99) and Boomboxes ($18.99) from upcycled M&M’s, Skittles and Starburst candy wrappers. Upcycling means using materials that would otherwise go to waste—in this case, excess packaging. Light, portable and super-colorful, the speakers and boomboxes are a natural complement to any iPod or MP3-player gifts this Christmas. They’re also battery-free, drawing power from your device to boom your sweet sounds—and packed and shipped flat to reduce pollution. —Brita Belli CONTACT: DwellSmart.
